Özet

The dynamic viscosities of aqueous polyethylene glycol, aqueous bovine serum albumin, and polyethylene glycol-bovine serum albumin-water solutions were measured at temperatures of 15, 20, 25, 30 and 35 degreesC. To estimate the viscosity values of polyethylene glycol-bovine serum albumin-water solutions, a one parameter Grunberg-like model which was satisfactorily used earlier by the present author for polyethylene glycol-dextran-water solutions was employed. The disposable parameter a for our temperature range was estimated as 3.71. The relative errors varying from 0.29 to 18.98 in absolute value indicates that the Grunberg-like model works perfectly for polymer-protein solutions as well. (C) 2004 Elsevier B.V.
